Background Art

[0002] Most of the existing dikes in China were built relatively early, and some even date back to the Han and Tang dynasties. With the development of the economy and society and the continuous expansion of the population and economic scale around the dikes, many dikes need to be upgraded and reinforced to meet the needs of economic development. Restricted by factors such as the original construction technology and the quality of backfill materials, many dikes have problems of seepage stability and need anti-seepage reinforcement. There are often various pipelines passing through the dike bodies and foundations of some dikes, and there are also cultural relics of historical value under some ancient dikes. If technologies such as cement mixing piles and high-pressure jet grouting piles are used for reinforcement, it will affect or even damage the pipelines, cultural relics, etc. In addition, the land use cost of the widening reinforcement method is high.
